PulseX 5W UV — Ultraviolet Laser

PulseX 5W UV is an industrial laser source primarily designed for ultra-precise marking and engraving of non-metallic materials and certain specialized surfaces.

The device operates using "cold processing" technology, which enables marking without burning or causing significant thermal damage to the material. [1, 2]

Main Technical Specifications

• Laser Power: 5W (5 Watts). This power level is ideal for performing highly detailed work on sensitive materials.

• Wavelength: 355 nm (ultraviolet spectrum). Thanks to this wavelength, the laser produces an extremely small focal spot, minimizing thermal deformation of the material.

• Marking Speed: Up to 12,000 mm/s.

• Working Area: Standard 110 × 110 mm (may vary depending on the lens used).

• Beam Quality (M²): < 1.2. This indicates excellent beam quality and highly precise focusing capabilities.

• Cooling System: Air Cooling. Models equipped with this system do not require an additional water chiller, simplifying equipment operation and maintenance.

Applications and Supported Materials

Ultraviolet lasers are ideal for processing sensitive materials that may be damaged by other types of lasers, such as Fiber or CO₂ lasers.

PulseX 5W UV is effectively used for the following materials:

• Plastics and Polymers: ABS, PVC, polypropylene, and others. Used for marking electronic housings, adapters, keyboards, and various plastic products.

• Glass and Crystal: High-precision micro-engraving on glass surfaces, as well as internal 3D marking inside crystals when the appropriate technology and equipment configuration are available.

• Electronics (PCB): Marking microchips, electronic components, and printed circuit boards with minimal risk of damage.

• Other Materials: Ceramics, leather, rubber, and certain metals with specialized coatings.

Main Advantages

1. Photochemical Ablation (Cold Processing)

Unlike traditional laser processing methods, ultraviolet lasers interact with materials primarily by breaking molecular bonds rather than relying solely on heating and melting.

This significantly reduces the risk of:

• Material burning.

• Surface discoloration or darkening.

• Melting and deformation.

• Damage to small and sensitive components.

2. Support for Popular Graphic Formats

The equipment supports commonly used graphic file formats:

• AI

• BMP

• DWG

• DXF

• PLT

This allows users to work with various vector and raster images for marking and engraving applications.

3. High Marking Precision

The laser enables the marking of extremely small text, logos, serial numbers, and other elements with exceptional detail.

Text marking with character sizes as small as 0.15 mm is possible while maintaining high sharpness and readability.

Service Life of the PulseX 5W UV Laser Source

The average service life of the PulseX 5W UV ultraviolet laser source is approximately 20,000 to 30,000 operating hours.

The actual lifespan depends on the intensity of use, operating conditions, and regular maintenance.

Service Life Based on Operating Schedule

• Operating 8 hours per day: Approximately 7–10 years.

• Operating 16 hours per day (two-shift operation): Approximately 3.5–5 years.

Note: These estimates assume daily operation without days off.

Comparison with Other Laser Types

Ultraviolet lasers generally have a shorter service life compared to Fiber lasers, which can achieve operating lifespans of up to 100,000 hours.

This is due to the natural wear and degradation of optical components and UV crystals used in ultraviolet laser sources.

However, UV lasers generally offer a significantly longer service life than many CO₂ lasers, particularly models equipped with glass laser tubes.

Conclusion

PulseX 5W UV is an efficient industrial solution for high-precision marking and engraving of sensitive materials, combining exceptional detail, minimal thermal impact, and a long operational lifespan.
